It is intended to guarantee

21、 consumer protection, minimize the hygienic and toxicological risks (see annex A) and avoid reduction of food quality. 1 Scope This European Standard specifies the thermal and hygienic requirements and test methods for transport units used for short-time transportation of catering containers. Foodst

22、uffs are packaged in these catering containers, complying with EN 631-1, which are fitted with a cover (e.g. lid) to prevent spillage. This standard is applicable for local and short-time delivery only. NOTE Attention is drawn to the EU-directives mentioned in annex B. 2 Normative references This Eu

23、ropean Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publication

24、s apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

25、rameters ISO 4288:1996, Geometrical Product Specifications (GPS) Surface texture: Profile method Rules and procedures for the assessment of surface texture 3 Definitions For the purposes of this standard the following definitions apply. 3.1 transport unit movable equipment with or without additional

26、 thermal maintenance to hold catering containers in order to transport them 3.2 local and short-time transportation movement of a transport unit from the preparation area to the consumer area within 3 hours 3.3 food area area composed of surfaces in contact with foodstuff NOTE 1 The food area also i

27、ncludes the surfaces with which part of the foodstuffs may come into contact under intended conditions of use, after which they may return into the foodstuffs. NOTE 2 The catering container, covered with a tight lid, is a food area. 3.4 splash area area composed of surfaces on or along which parts o

28、f foodstuffs may splash or flow under intended conditions of use and do not return into the foodstuffs NOTE An example is the inside area of the transport unit when the lid or door is shut with the catering containers removed. 3.5 non-food area any area which is not intended to come into contact wit

29、h foodstuffs and is not a splash area 3.6 cleanable designed and constructed so that soils are removed by recommended cleaning methods 3.7 disinfection inactivation of pathogens and other micro-organisms to achieve hygienic conditions 4 Requirements 4.1 Materials Materials shall be resistant to food

30、stuffs and normal wear and tear. Surfaces of materials and coatings shall be durable, cleanable and, if necessary, shall be capable of being disinfected. They shall be in a sound condition (e.g. have no breaks, cracks, or strikes) and be resistant to cracking, chipping, flaking and abrasion and prev

31、ent penetration of unwanted matter under intended use. The materials shall be resistant to appropriate cleaning substances and disinfecting agents. The materials: shall not transfer undesirable odours, taste, colours or taint to the foodstuffs; shall not contribute to the contamination of foodstuffs

32、 or have any adverse influence on the foodstuffs. 4.2 Design and construction 4.2.1 General All surfaces including all removable parts, when fitted, shall be accessible for cleaning and disinfection. Moreover, their assembly shall allow liquids to drain off completely from the outside of the transpo

33、rt unit (in an inclined position, if necessary); if this is impracticable due to weight restrictions, an effective drainage system shall be provided.Page 4 EN 12571:1998 BSI 05-1999 4.2.2 Surfaces of the splash area All surfaces shall present surface roughness R a ,a s defined in ISO 4287 and measur

34、ed according to ISO 4288, not greater than 6,3mm. The arrangement of the surfaces shall be such that no product particles (foodstuffs or cleaning product) can become trapped in small crevices becoming difficult to dislodge and so introducing a contamination hazard. Adjacent continuous, inner surface

35、s and corners shall have a minimum radius of 2 mm. Joints between inner surfaces (e.g. side and base) shall be made in the vertical sides at a suitable distance from the base radius. The joints shall be continuous, smooth and free of crevices. 4.2.3 Non-food area All equipment shall be designed and

36、constructed in such a manner as to prevent the retention of moisture, ingress and harbourage of vermin and soils and to facilitate inspection, servicing, maintenance, cleaning, handling and transportation. Tubular framing shall be totally closed, effectively tightened or sealed. 4.3 Thermal characte

37、ristics Transport units shall meet the following thermal requirements independent of their materials and design and regardless of the way in which maintenance of the inner temperature is achieved. During and after 3 h transport at the ambient temperature stated in 5.1, the temperature of the content

38、s of each catering container shall comply with the values given in Table 1. Table 1 Thermal class Condition Behaviour of temperature A Hot # 10 K decrease B Cold # 4 K increase C Deep frozen # 4 K increase For the cold condition, the temperature of the contents shall remain within +38C and +78C. The

39、se requirements shall be verified by use of the tests described in clause 5. 5 Test of thermal characteristics 5.1 Test conditions Transport units shall be preconditioned at an average ambient temperature of (25 0,5)8C, with a maximum dispersion of 28C. This temperature is the arithmetic mean of the

40、 temperatures of two probes located at 0,10 m from the geometric centre of the inner surfaces of two external adjacent walls of the transport unit; it shall be placed at least 0,20 m from the ground. The tests shall be carried out in still air defined by a stirring up rate between 10/h and 20/h. NOT

41、E Stirring-up rate = air flow (m 3 /h)/volume of the test room (m 3 ), measured in normal atmospheric conditions. For insulated transport units with additional thermal maintenance, the additional thermal maintenance means shall be fitted in accordance with the manufacturers requirements as given in

42、the instruction handbook before starting the measurement. 5.2 Preparation The transport unit shall be loaded in such a way that the ratio between the volume of the test load and the inner volume of the transport unit is equal to (50 5) %. If not otherwise stated, the test medium shall be water. For

43、the test load, a minimum number of catering containers made of stainless steel shall be used. The containers shall have the same size and the test load shall be distributed equally. The catering containers filled with the test medium and their lids shall be preconditioned at a temperature of: a) 28C

44、 higher than the initial reference temperature (see 5.3), with a maximum dispersion of 18C, for hot conditions; b) 28C lower than the initial reference temperature (see 5.3), with a maximum dispersion of 0,58C, for cold conditions and for deep frozen conditions. The measuring test points shall be lo

45、cated at the geometrical centre of the test load of each catering container. Immediately prior to the measurement, the transport unit shall be closed. 5.3 Measurement The measuring points shall be located at the geometrical centre of the test load of each catering container. The accuracy of the temp

46、erature measurement instruments shall be# 0,5 K. The lids and doors of the transport unit shall be kept closed during the test. a) Hot conditions Initial reference temperature: 758C Final reference temperature: 658C b) Cold conditions Initial reference temperature: 38C Final reference temperature: 7

47、8C c) Deep frozen condition The tests shall be carried out with diluted glycol (50 % glycol, 50 % water) instead of water. Initial reference temperature:2228C Final reference temperature:2188C The test results are positive if the temperatures of the contents of all catering containers remain within

48、the indicated values (see 4.3) during the test time of 3 h.Page 5 EN 12571:1998 BSI 05-1999 1) Such marking is a claim of compliance with EN 12571:1998 but does not imply CEN approval of the product; the accuracy of this claim is therefore solely the responsibility of the person applying the marking

49、. 6 Verification of hygiene requirements Verification of compliance with hygiene requirements shall be undertaken by: a) visual inspection, b) check of material specification, c) measurement (e.g. temperature, surface roughness), d) practical and functional tests, where appropriate. 7 Operating instructions Each transport unit shall be supplied with operating instructions. These instructions shall be brief and easily comprehensible. They shall contain at least the following: a) guidance on how t
